The composition of electric minivan includes: electric drive and control system, driving force transmission and other mechanical systems, and working devices to complete established tasks. The electric drive and control system is the core of electric vehicles, and it is also the biggest difference from vehicles with internal combustion engines. The electric drive and control system consists of a drive motor, a power supply, and a speed control device for the motor. The other devices of electric vehicles are basically the same as those of internal combustion engine vehicles.
The function of the electric minivan transmission device is to transmit the driving torque of the electric motor to the drive shaft of the automobile. When the electric wheel drive is adopted, most parts of the transmission device can often be ignored. Because the electric motor can be started with a load, the clutch of a traditional internal combustion engine vehicle is not needed on an electric vehicle.
Because the rotation of the drive motor can be changed through circuit control, the electric vehicle does not need the reverse gear in the internal combustion engine vehicle transmission. When the stepless speed regulation control of the electric motor is adopted, the electric vehicle can ignore the transmission of the traditional vehicle. When using electric wheel drive, the electric vehicle can also omit the differential of the traditional internal combustion engine vehicle transmission system.
2. Driving device
The function of the driving device is to turn the driving torque of the motor into a force on the ground through the wheels to drive the wheels to walk. It has the same composition as other cars, consisting of wheels, tires and suspension.
3. Steering device
The steering device is set up to realize the turning of the car, and consists of a steering gear, a steering wheel, a steering mechanism, and a steering wheel. The control force acting on the steering wheel deflects the steering wheel to a certain angle through the steering gear and steering mechanism to realize the steering of the car. Most electric vehicles use front-wheel steering, and electric forklifts used in industry often use rear-wheel steering. The steering devices of electric minivans include mechanical steering, hydraulic steering and hydraulic power steering.
